tomcat - 我的 JUnit 测试如何找到我的 Tomcat 数据源？

Question

我正在尝试测试我的 REST 服务。我正在使用 Jersey2 的 JerseyTest 和提供的 JDK HttpServer 框架。我需要测试来访问在 META-INF/context.xml 中定义的数据源。服务部署在 Tomcat 上。

如何将 ContextConfig 添加到 ResourceConfig 使其正常工作？

这是设置代码，目前不起作用。上下文似乎没有注册。

@Override
protected Application configure() {
    ResourceConfig rc = new ResourceConfig(OfficeSpaceService.class);
    rc.property("contextConfigLocation", "src/main/webapp/META-INF/context.xml");

    return rc;
}

这是测试代码:

@Test
public void getSpacesTest() {
    Response response = 
        target("v1/space/")
        .request()
        .get(Response.class);

    int status        = response.getStatus();
    MediaType mt      = response.getMediaType();
    String spacesJson = response.readEntity(String.class);

    //Assertions here.
}

这是服务尝试查找数据源时的异常:

Answer 1

有一种方法:

ResourceConfig rc = new ResourceConfig(OfficeSpaceService.class);
rc.property("contextConfig",new ClassPathXmlApplicationContext(
new String[]{"src/main/webapp/META-INF/context.xml"},
ContextLoader.getCurrentWebApplicationContext()));
